    • The present invention relates to an antenna switching apparatus in a spatial modulation method capable of minimizing signal distortion by asynchronous switching time by controlling the delay time of a switching control signal applied to each switching unit by analyzing a signal outputted from the switching units connected to multiple antennas. To achieve this, the present invention provides the antenna switching apparatus in the spatial modulation method comprising: a control signal generation unit to generate a switching control signal; the multiple switching units installed at the front ends of each of the antennas to apply a transmission signal to the antennas by executing switching operation according to the switching control signal; a delay analysis unit to calculate delay information for synchronizing the switching control signal applied to the multiple switching units by receiving the transmission signal outputted from each switching unit; and a delay control unit to individually apply the switching control signal to each of the switching units by synchronizing the switching control signal according to the calculated delay information.
